The object of my invention is'toprovide a check row planter which is simple, durable and comparatively inexpensive to manufacture.

5' A further object of my invention is to provide a check row planter for planting grain without the necessity of using wire stretched across' the field to be planted and having buttons at intervals to drop the grain m from the planter into equally spaced hills. Still a further object is to provide mecha# nism for dispensing' grain from the planter,

such mechanism being operatedy from the traction wheels of theplanter through a' ii-,i clutch mechanism which maybe disengaged when transporting the planter fromone position to another .orthe like.

Still a further object is to provide ing mechanism to indicate the positionsof 01 the planted hills Vof grain', the mechanism being arranged Vvfor upwardy movement relative toA theeplanter frame iin the event it strikes an obstruction.f Still a further object is to provide the.

means for actuatii'ig the grain dispensing mechanism whereby hills of grain being? planted may be checked with hills of grain already planted in a previousro'iind;

3g. Still a further Objectis to' provide a" novel intermittent operating iilech'anisni for driving the grain dispensing mechanism from they continuously rotating tracti'onwheels of the planter.

A main shaft 12 is journalled on the frame 10 and `trac ti`on wheels 14 are journalled on the Shaft 1 2.

A tongue 22 is-provided for pulling the planter and cross frame members 24 are p'rO. 85% vided for supportingv grain receptaclesl26 and furrow shoes 28. grain dispensing mechanism consisting of a rotating plate 30 With' a series of openings toreceive grain from the receptacles 26 and discharge it *ii'ito'` passagewaysl 3 2 is provided; Bevel gear teeth are formed on the rotary plates 3 0"fo`r coact-ion with bevel pinions" 34' whichV are' mounted on a shaft 36. The shaft 3 is driven through a chfaii' connection 38 froina shaft 40'` having-'a star wheel 42 thereon and a pinion 44 having t'wo teeth for each point of the`rv star wlieelm42.k The starw'lied iaiiiayb three-pointed s' illustrated or have any number of point'sde- 93" sire'd kand each curved surfacebetweenx two;

chain 64 from the main shaft 12. Collars 66 prevent longitudinal movement of the clutch cone relative to the clutch shaft 52 but allow free rotary movement of the cone relative thereto.

j A clutch pedal 68 is provided having cam surfaces 70 which coact with a cam collar '.72 which is secured to the clutch shaft 52. Rotation of the shaft 52 is prevented by a key v74E in one of the bearings for the Y'clutch frame 10. rlhe shaft 12 extends loosely shaft. A spring 75 is provided to cause the collar 66 to force the cones 58 and 60 into engagement whereupon the cam collar 7 2 assumes a position adjacent the cam surface 70. Means for manually adjusting the Vclutch is provided in the form of a pinion 76 on the clutch member 58 meshing with a gear 7 8.

The gear 7 8 is freely rotatable on the main shaft 12 and is driven from the clutch whenever the clutch is in motion. A lever 80 is freely rotatable on the main shaft 12 and normally held in any position'to which it may be moved by a pair of friction bars 82. The friction bars 82 are anchored at 84 to the through them and they are mounted on opposite sides of the lever 80. Their free ends are provided with a bolt 86 and spring 88 whereby to cause friction of the bars 82 on the lever 80 for normally holding itin a stationary position. n

A dog 90 is slidably mounted on the lever 80 and normally held raised by a spring 92. The dog 90 may be lowered by manual actuation of a finger 94 against the action of a sprinof 92.,v j

' n Practical operatz'onV In the operation of my device, assuming the planter to be 'in use, the traction wheels 14 through the pawls 18 drive the main shaft 12, rotation of which is imparted to the clutch member 60. The clutch member 60 is in frictional engagement with the cone 58 for rotating the notched disk 46 whereby each revolution of the notched disk will impart a partial revolution to the stary wheel 42 by means of the teeth 50 engaging the pinion 44. This will cause intermittent rotation of the shaft 40, the shaft 36, the grain dispensing disk 30 and a grain dropping wheel 96 in the bottom of the planter shoe 28 which is driven by a chain 98 from the,v shaft 36. Thus Vthe grain .will be lintermittently dropped from the wheel 96, the wheel being quite close to the ground to prevent any uncertainty in the positioning of the hill of grain caused by a long travel of the grain after being dropped.

Thus the hills will be periodically spaced throughout the length of the field being planted.

- The spoke arms 1001of a marking shaft 102 will indicate the positions of the hills by making marks in the ground surface which can be seen when the neXt row of grain is planted sopas to check the hills crosswise of the held. If the hills are out of alignment, the clutch pedal 68 can be depressed for allowing th'e planting mechanism and marking mechanism to stop momentarily for adjusting the hillsrbackwardand if it so happensv that they must be adjusted forward, the lever 80 is then manipulated with a rearward motion (the dog 90 being depressed into a tooth of the gear 78) to effect such forward adjustment. I Y

vSprings 104 are provided torallow, upward movement ofthe marker shaft 102 in the event of striking an obstruction in the field. The bearings 1064for the vmarker shaft 102 are vertically slidable relative to supporting brackets 108.. A chain connection 110 is Vprovided Ybetween the clutch and the marker' shaft 102. 'A chain tightener 114 is provided to allow upward movementof the marker shaft 102 and yetkeepthe operation of the marker properly timed with the rest of the planter mechanism. The'various sprockets and gears are, of course, of the p'roper'pro'- portional sizes to obtain timing of the mechanism to drop the grain at specified intervals as desired.

Some changes may be made in the construction and arrangement of the parts of my devicerwithout departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which ,may be reasonably included within their scope. e

I claim as my' invention: y

2'. In a check row planter, a frame, traction wheels therefor, a clutchY shaft journalled thereon, a clutch on said shaft, a grain con tainer, mechanism for dispensing grain therefrom, an operative connection between said clutch and said mechanism, a lever for manually adjusting said clutch and having a normally retracted dog Which may be manually extended When it is desired to adjust the clutch, a pair of bars anchored to said frame and positioned on opposite sides of said lever and spring means constraining said bars to engage said lever to thereby retain said lever in a osition of rest.

3. n a cheek row planter, a frame, traction Wheels therefor, a clutch shaft slidably supported thereon, means for preventing rotation of said clutch shaft relative to said frame, a clutch member rotatable on said shaft and driven from said traction Wheels, a second clutch member thereon for coaction with the first clutch member, a grain container, mechanism for dispensing grain therefrom, an operative connection between said second clutch member and said mechanism, a spring for holding said clutch members in Contact with each other, a clutch pedal rotatable on said clutch shaft and having a cam member, and a cam member coacting there- With and secured to said clutch shaft whereby rotation of the clutch pedal and its cam member will slide the clutch shaft against the action of said spring.
